In
the United States, the embodiment of permaculture can be found at a
450-acre parcel - the Quail Springs Permaculture Farm - tucked into a piņon- and
juniper-covered canyon in Southern California's Cuyama Valley, 32
miles "as the raven flies" from the Pacific Ocean and about
60 miles northwest of Los Angeles.
Here at the base of two "sister mountains" on a windswept
desert-like terrain sacred to the area's native Chumash Indians live
14 permanent residents, mostly teachers and "land stewards,"
along with a handful of interns. All work to restore a landscape laid
waste by a century of clear-cutting and grazing, while also hosting
seminars and workshops on topics ranging from safe water and green
building to creating a carbon economy.
It's applied
permaculture, a design science focused on integrating sustainable
shelter, energy, food and water for human settlement.
The idea took shape back in the mid-'70s when Bill Mollison, a
University of Tasmania lecturer in environmental psychology, and
student David Holmgren began collaborating on how to combat the ills
of modern industrial agriculture. Their solution was
"permaculture" - for "permanent agriculture" -
which they outlined in a 1978 book, Permaculture One: A Perennial Agriculture
for Human Settlements. Originally focused on farming methods, permaculture
has since evolved to embrace all aspects of human survival.
At Quail Springs,
days are spent perfecting greywater systems, creating food forests and building bio-swales to keep the limited rainwater
from eroding the topsoil. But what's really capturing attention are
the buildings constructed with natural products like straw bale, adobe
and bamboo.
But don't expect to see this eco-village-in-the-making take final form
in your lifetime - or your children's or your grandchildren's -
and certainly not in the lifetime of the farm's founders,
husband-and-wife team Warren Brush and Cynthia Harvan.
Brush says the undertaking will take 200 years.
"The elders in
my life have always shared the idea that a village can't be started in
one generation," he explained. The 44-year-old Santa Cruz native
says seven generations are needed to bring the necessary cohesiveness
between the people and the land.
"That kind of long-term thinking and relationship with place
changes how you do everything. And that's a lot of the impetus for
what's driving us to use natural as opposed to conventional building
processes."
No wonder Quail Springs emphasizes exploring methods and materials
that not only preserve natural resources but that can last centuries.
Indeed, Brush can be heard frequently citing one rather disarming
statistic from the American Contractor's Association Web site:
"The average home built conventionally today will only last 40
years before needing to be rebuilt."
This won't work if you have a 200-year plan.
The
Beginning
Quail Springs' story begins in 1997 when the couple established the
Wilderness Youth Project at a Santa Barbara shelter for homeless
families. The idea was to help young people experience the personal
and practical benefits of exploring the natural world, using a ranch
owned by one of the donors. The site (adjacent to Quail Springs) was
perfect for helping kids practice animal tracking, food foraging and
other survival - or as Brush terms it, "origin" -
skills.
After several years,
Brush - a pre-med student at the University of California, Santa
Barbara, who ended up majoring in botany - noticed that participants
were asking for more. "They wanted to know how to apply the ethic
of earth and people care to a modern context in the middle of Santa
Barbara or L.A. That really unlocked something with my wife, Cindy,
and me. We both had this overwhelming feeling that there needed to be
this next step."
In May 2004, with
the help of the locally based Zannon Family Foundation, Brush in purchased 160 neighboring acres
and began his nonprofit grand oeuvre.
To help fulfill its need for healthy, eco-friendly housing and
"foster" as Brush says, "independent, entrepreneurial
ways of approaching how we keep ourselves alive," they brought in
Justin Kirmse and his partner Lyn Giesecke in 2008 to found
the Living Craft
Project. For
Kirmse and Giesecke, the goal was clear-cut: to teach the art of
natural building and authentic living. This meant pursuing "the
simplest path between the land, our hands, our relationships and what
physically sustains us - shelter, water, fire and
food."
That also requires a
commitment to move away from toxics. Brush cites Paula
Baker-LaPorte, a
Quail Springs consultant (she and her husband have been
promoting
"EcoNests" made of clay, straw and wood since 1994) and author
of
Prescription for a Healthy House, who says the typical home uses a minimum of 10,000
toxic chemicals when all the paints, glues, carpets, caulking, etc.,
are factored in.
And though the endeavor may sound dreamily utopian, the project is as
pragmatic as it gets, offering hands-on instruction to transform
anyone interested into the ultimate do-it-yourselfer. Last summer the
Living Craft Project launched its first apprenticeship project with
six apprentices in their late teens to mid-30s from the United States
and Belgium. After getting certified following a 72-hour permaculture
design course, Kirmse and Giesecke worked with the team to construct a
350-square-foot straw bale structure (with 100-square-foot light
clay-straw attached bedroom) for a young family that stewards the land
at Quail Springs.
Meeting the
Building Code
Known for its low-cost, easy availability and high insulation value,
straw-bale construction got its start in the United States in the
early 1900s following the invention of steam-powered bailers in
Nebraska. And though it flourished until construction became
industrialized in the 1950s, it enjoyed a resurgence in the 1970s.
Unfortunately, straw-bale construction is illegal in several states,
including California. At Quail Springs, local officials have postured
over unmet building codes, especially those dealing with earthquake
safety.
Jim MacDonald,
director of the Ventura County Building and Safety Division, said that
one of the problems is that building codes are just now starting to
catch up with green building techniques. "I'm all for alternative
building materials, but I have to be satisfied that it complies with
state law. Unfortunately, this presents some difficult rigors to
applicants."
It doesn't help that
Quail Springs is located just 11 miles from the San Andreas Fault,
the
seismic spine of the
Golden State.
Brush, though, says
engineering tests at the University of Nevada's Large-Scale Structures
Laboratory found
that load-bearing straw bale - the same type built at Quail Springs
- demonstrated the highest earthquake resistance of any buildings
they'd ever
seen, and want to
see the construction fostered in the more rattling parts of the globe
like
Pakistan.
So not only isn't
Brush concerned about the Big One - he's looking forward to it.
"We said codes or no codes, we're gonna build this because we're
near the fault line, and we'd love to see it go through an earthquake
and be able to have that data for other people to learn
from."
His go-to-it
attitude isn't uncommon among alternative-home gurus; witness the
legal travails of Earthship inventor Michael Reynolds.
Not that Brush wants
to continue going rogue. With the backing of David Eisenberg (chair of
the codes committee for the U.S. Green Building Council) Brush is working with local politicians to
put pressure on the state to adopt legislation exempting Quail Springs
and other research organizations from building-code requirements.
Several local universities, including California Polytechnic
University and the University of California, have partnered with Quail
Springs to test out buildings and sustainable systems that would
otherwise be illegal.
"We really want
to work with the building department in sharing the data that we're
gathering. I'd love to be able to sit down with Jim MacDonald minus
the barriers he has of trying to enforce a code that is no longer
relevant to our times ecologically," Brush said.
